To all whom t may concern Be it known that I, CHARLES M. I-Innrnn, a resident of Butler, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Rope-Sockets, of which the following is a. specification.

The primary object of this invention is to provide a rope socket which may be quickly and conveniently manipulated for either securing or releasing the rope.

In operating a pump with a wire rope or cable, the latter having largely superseded sucker rods, it is frequently necessary to connect and disconnect the cable and its socket, particularly when the cable works through an oil saver.

The socket herein proposed provides for quickly releasing the cable, and for securely holding it when in place.

In the accompanying drawings, Figure 1 is an elevation of the improved socket shown in position in a well tube. Fig. 2 is a longitudinal section of the socket, and Fig. 3 is a cross-section on line 3-3 of Fig. 2. Fig. i is a longitudinal sectional view of a portion of the clamp illust-rating a cross key or pin of modified construction.

Referring to the drawings, 2 designates the body of the rope socket, provided with means at its lower end for attaching any suitable tool 3, such as a sinker bar, jars, or a pump. The attaching means at the lower end of the body may consistof a threaded box 5.

A tixed rope-clamping jaw 6 is provided by extending one side of the body upwardly as shown, the body being recessed at 7 at the base of this extension to receive hinge arm 8 on the lower end of movable jaw 9, the hinge arm mounted on pin 10, and the parts so shaped that jaw 9 may turn outward to position shown in dotted lines, Fig. 2, for releasing or admitting' the cable 11.

Jaws 6 and 9 are threaded externally to receive the jaw-clamping nut 12, and theyare preferably tapered upwardly, forming aff truncated cone when closed together, the

bore of nut 12 being correspondingly tavpered, thereby clamping or wedging the caf ble when the nut is tightened.

In the preferred construction, a pin 15 ist' driven through the cable above extremity winding 11. The length of the pin corresponds to the diameter of body 2, and the extremities 15 thereof are confined in half-round cavities in the faces of the jaws, sothat when the jaws are closed the pin eX- tremities are locked. While the hold might be suficient wit-hout this cross pin, it makes the connection absolutely secure. The bulge in the cable formed by the pin is received in enlargement 19 of the socket. In Fig. 4 a key 18, corresponding in length to the diameter of the cable, forms a bulge in the cable which is received in cavity enlarge ment 19 of the jaws.

The inner or cable holding faces oitl the jaws may be variously formed. In Figs. 2, 3, and 4L they are indented or recessed, as indicated at 13, to conform to the spiral surface of the cable, the base 14 of the recess being' slightly enlarged to receive the cable winding.

In each adaptation the rope is securely and positively held when clamped between the jaws, yet is readily removable when the nut is loosened and the movable jaw turned outward as in Fig. 2.

I claim:

l. The combination with the separable jaws of a rope socket forming a cable space therebetween with the meeting faces of the jaws recessed to form a closed pin passage when the jaws are fitted together, and means for clamping the jaws on the cable, of a cable consisting of strands twisted together with their extremities wrapped with a binding', and a pin extending through the 'cable' adjacent to the binding and laterally enlarging the cable into the space between the jaws with the ends of the pin projecting from opposite sides of the cable and into ,the pin passage formed in the meeting faces of the jaws.

2. In a rope socket for well drilling, the

" `combination of a socket body adapted at its flower end to connect with a well tool and itsupper end shaped to form a jaw, a movfable jaw adapted to coperate with the bodyjaw, a cable, the inner faces of the jaws shaped to embrace the cable, the adjacent faces of the jaws recessed to form pin Vpassages at opposite sides of the cable space with a port-ion of each passage in each jaw, V a transverse pin secured to and projecting from opposite sides of the cable, the cable In testimony whereof I aix my signature and the pin carried thereby being yentered in presence of two Witnesses.

between th when opn with the 'n L the plane of thea pin passages in the jaws, CHARLES M' HEETER' and means for clamping thet jaws onfqhe Vitnesses: cable with the pin recesses in the jaws AClos- J. M. NESBIT, ing around Jche projecting ends of said pin. l F. E. GAITHER.
